Texas Integrated Report for Clean Water Act Sections 305(b) and 303(d)

Formerly called the "Texas Water Quality Inventory and 303(d) List," the Integrated Report evaluates the quality of surface waters in Texas, and provides resource managers with a tool for making informed decisions when directing agency programs.

The Texas Integrated Report describes the status of Texas’ natural waters based on historical data. It identifies water bodies that are not meeting standards set for their use on the 303(d) list.

The Texas Integrated Report satisfies the requirements of federal Clean Water Act Sections 305(b) and 303(d). The TCEQ produces a new report every two years in even-numbered years, as required by law. The 303(d) List must be approved by the EPA before it is final.

An advisory group worked with the TCEQ on updates to the “Guidance for Assessing Texas Surface Water Quality.”
